SPRING-PEDAL.

SPECIFICATION forming part of Letters Patent No. 553,797, dated January 28, 1896. Application iiled Tune l0, 1895. Serial No. 552,333. (No model.)

'art to which itappertains to make and use the same.

My invention relates to improvements in lspring-pedals for bicycles, tricycles, or any machinery driven by foot-power, and it consists of a spring foot-plate applied to the pedal and in certain novel features which will be hereinafter fully described and claimed.

Referring` to the accompanying drawings, in which like letters of reference designate corresponding parts in the several views, Figure l represents a perspective View of my improved spring-plate applied to the pedal of a bicycle. Fig. 2 represents aperspective view of the spring-plate and its clampingscrew detached. Fig. 3 represents a perspective view of a modied form of spring-plate, showing a pair of the said plates attached to the pedal of a bicycle.

A designates the crank, A the sprocketwheel, and A2 the pedal-pin of a bicycle.

The pedal B consists of a sleeve B' which passes over the pedal-pin and has the bearings inclosed therein, end plates b, and connecting-plates b.

The spring-plate C is formed, as shown in Fig. 2, with a foot-plate C', having the points c turned up to prevent the foot from slipping, and the spring portion C2 extending back from the said foot-plate, bent over upon itself as at O3, extending forward as at C4, and finally terminating in a downwardlyprojecting lug O5, which latter is perforated to receive the clamp-screwD. The foot-plate O may be perforated as shown to diminish the weight. The spring-plate is attached to the pedal by means of the clamp-screw D, which passes through the lug O5 and one of the connecting-plates b', and receives a nut d on itsinner end, thus clamping the end of the spring-plate to one of the connecting-plates, as shown in Fig. 1.

In Fig. l I have shown a single spring-plate attached to the pedal, but it will be obvious that, if desirable, one such plate may be attached to each 0f the connecting-plates, one extending above and the other below the pedal, so that one will balance the other and facilitate the placing of the foot upon the foot-plate O.

In Fig. 3 I have shown a slight modification of the device, in which case the pedal is provided with connecting-rods b2 in lieu of the plates Z2', and the footplates C are formed with spring-plates c2 extending both forwardly and backwardly and bent round beneath the foot-plate as at c3, and'iinally bent back upon themselves to form the hooks c4, which are sprung over the connecting-rods bthus holding the spring-plates in position. In this instance I have shown two springplates, one above and one below the pedal, in which case the hooks c4 of one plate are sprung over the corresponding -hooks of the other. It will beiobvious that only one of these plates may be used if desirable.

It will be understood that I do not wish to confine myself to thc precise construction shown in the drawings, as various modifications may be made in the form, shape, or method of attachment without departing from the spirit of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. The combination with apedal, of afootplate having a spring extension bent round under the said plate and attached to the pedal, substantially as described.

2. The combination with a pedal, of aperforated foot-plate having points turned up to prevent the foot from slipping, and spring extensions from the said foot-plate bent round beneath the said plate and attached to the pedal, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
